Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape recorder having a mechanism capable of recording and reproducing in a forward direction and a reverse direction with a tape mounted.

2. Description of the Related Art In recent years, an auto-reverse type tape recorder is often used because of its good operability, which automatically shifts to tape running on the reverse side when tape running on the forward rotation side ends during recording or playback. However, with the conventional auto-reverse type tape recorder, when moving from the recording pause mode to the recording play mode, it is possible to directly move from the recording pause mode on the reverse side to the recording play mode on the reverse side or the recording play mode on the normal side. There are some tape recorders and tape recorders that can move from the recording pause mode on the reverse side to the recording play mode on the reverse side but cannot directly move to the recording play mode on the forward side.

Problems to be Solved by the Invention However, the tape recorder that can directly record from the normal recording side to the reverse recording side by moving directly from the reverse recording pause mode to the normal recording recording play mode, After performing the recording pause operation, if the switch for recording play on the forward rotation side is mistakenly pressed, there is a serious problem that the previously recorded portion is erased and a new recording is performed.

Also, if the tape recorder that cannot switch from the reverse recording pause mode to the normal recording play mode is in the reverse recording pause mode when you try to start immediate recording when the running direction immediately before recording is the reverse side. Since it does not directly move to the normal rotation recording play mode, there is a problem that the troublesome operation of moving the running direction to the normal rotation side once, then changing to the normal rotation side recording pause mode and moving to the recording play mode, In the case of FM broadcast recording, there was a problem that the opportunity to start recording was lost.

The present invention has been made in view of the above point, and it is possible to shift from the reverse recording pause mode to the normal recording play mode only at the start of recording, and when the reverse recording play mode is changed to the reverse recording pause mode after the start of recording, It is intended to provide a tape recorder which is in a normal reproduction mode without shifting from a reverse recording pause mode to a normal recording play mode.

Means for Solving the Problems In order to solve the above problems, a tape recorder according to the present invention includes a current mode memory section for storing an operation mode of a current mechanism section and a mechanism section immediately before shifting to the current operation mode. The old mode memory section that stores the operation mode of
A current mode memory determining unit for determining the contents of the current mode memory unit and an old mode memory determining unit for determining the contents of the old mode memory unit are provided. When the play operation switch is pressed and the normal play command is input to the switch input section, the control section is set so that the old mode memory section is in the normal recording play mode when the memory section is in stop mode or pause mode. A control signal is output, and when the old mode memory section is in the reverse recording play mode, the control output section releases the reverse recording pause mode to the mechanism section and controls the mechanism section to be in the normal reproduction mode. It was done.

Operation According to the present invention, when the forward rotation play switch is pressed when the current operation mode of the mechanism section is the reverse recording pause mode, the operation mode immediately before shifting to the current reverse recording pause mode is the old mode. Judging from the memory part, if the previous operation mode is the reverse recording play mode, it does not move to the normal recording play mode but moves to the normal reproduction mode, so there is no accidentally erasing the already recorded part. When the operation mode is the stop mode or the pause mode, the recording mode is switched to the normal forward recording play mode, so that a light operation at the start of recording is unnecessary and the opportunity of recording start is not lost.
